Title: Heating method in vacuum heat treating furnace
Inventor: KAWASAKI TOMOYASU
IPC: C21D1/773
Filed: 1986-09-14
Abstract: PURPOSE:To prevent the chipping of an edge made of a high-speed tool steel and the deterioration of the wear resistance by introducing a gas into a hardening furnace under high pressure when the tool steel is hardened and by rapidly heating the tool steel so as to prevent the coarsening of the grains. CONSTITUTION:When a high-speed tool steel is hardened by heating to a prescribed hardening temp. and rapid cooling, a hardening furnace is evacuated once to a high degree of vacuum after the tool steel is set in the furnace and the tool steel is heated to 950 deg.C in vacuum (stage I) by supplying electric current to a heater in the furnace. An inert gas such as N2 is then introduced into the furnace under high pressure and the tool steel is rapidly heated to about 1,200 deg.C hardening temp. under pressure (stage II). Since the furnace is filed with a high pressure atmosphere of the inert gas, the heating rate is high and the tool steel is rapidly heated to the hardening temp. without coarsening the grains. After the rapid heating, the tool steel is rapidly cooled (stage III) by utilizing the pressurized inert gas in the furnace as a cooling medium. Thus, the high-speed tool steel is hardened and the resistance of the tool steel to embrittlement and wear due to grain coarsening is improved.

Title: Polishing method for glasses frame
Inventor: SASAKI SHIGERU
IPC: G02B5/00
Filed: 1984-10-17
Abstract: PURPOSE:To make it possible to smoothly finish the surface of a glasses frame on a mounting plate by polishing by injecting abrasives comprised of a liquid absorbing soft member such as walnut shell shaped chips etc. together with the same liquid toward a glasses frame. CONSTITUTION:A driving motor 15 is driven to rotate mounting plates 9, 9a etc. in a polishing position in a box 3. In this state, a pump is driven to inject abrasives comprised of a liquid absorbing soft member such as walnut shell shaped chips etc. together with the same liquid through nozzles 16, 16a. In addition, a driving motor 18 is reversibly rotated to vertically reciprocate the nozzles 16, 16a through a rack.pinion mechanism 19 and a supporting lever 17 corresponding to the height of piled up glasses frames. Thus the abrasives collide against the glasses frames on the mounting plates 9, 9a etc. in different directions. In this case, the walnut shell shaped chips is caused to slide on the surface of the glasses frame because of the liquid lying between the chips and the frame. Consequently rubbing action acts on the glasses frame to smoothly finish its surface by polishing.

Title: Cleaning method for sludge-like deposited layer
Inventor: KATO JUICHI
IPC: C02F11/00
Filed: 1986-09-18
Abstract: PURPOSE:To permit easy cleaning by adding a porous adsorption assisting material and binder for pelletization to chaff ashes, forming a granular cleaning material having specific gravity, and dispersing the cleaning material into water, thereby settling a sludge-like deposited layer so as to cover the surface of said layer. CONSTITUTION:The porous adsorption assisting material (e.g., zeolite) is compounded with the chaff ashes as the essential component and the binder for pelletization (e.g., clay) is added thereto to form the granular cleaning material 3 adjusted to 1-2 specific gravity. Said material 3 is sprayed into water and is settled so as to cover the entire surface of the sludge-like deposited layer. The simple operation involving the spraying of the cleaning material onto the sludge-like deposited layer is merely necessitated according to the above-mentioned method and since the spraying of the cleaning material does not stir the sludge-like deposited layer, there is not transient sludge and the gravel base part by the cleaning material suppresses the activity of the sludge- like deposited layer for a long period of time. The water quality and sludge layer are thereby cleaned.

Abstract: PURPOSE:To surely separate and select products from unnecessary matters by a method wherein three pairs of rolls are arranged to the direction of flow of product, which is continuous in the form of string, under the condition that the rotational speed of the pair of intermediate rolls are set to be comparatively faster than that of the remaining pairs of the rolls so as to pull each connecting part between the product and the unnecessary matter. CONSTITUTION:Products D and unnecessary matters E, which are continuously delivered in the form of string from molds B, are introduced from a conveyor 31 between the foremost rolls 1 and 1' and then between the intermediate rolls 2 and 2'. At this time, since the rotational speed of the intermediate rolls 2 and 2' is set to be faster than that of the foremost rolls 1 and 1', the product D is strongly pulled, resulting in separating the product D from the unnecessary matter E. Next, the intermediate rolls 2 and 2' hold the unnecessary matter E between them, resulting in separating the unnecessary matter E from the connecting part between the unnecessary matter E and the following product D. After that, the product D and the unnecessary matter E are directed to the final end rolls 3 and 3'. In this case, since the interval between the rolls 3 and 3' and the intermediate rolls 2 and 2' is set to be shorter than the length of the product D and longer than that of the unnecessary matter E, the product D is held between the final end rolls 3 and 3' and the unnecessary matter E falls between both the rolls 2 and 2' and 3 and 3'.
